Lee Rannals for redOrbit.com — Your Universe Online Solar cells are nothing new, but what may be coming is a technology to make a less expensive version of them. Silicon is used in both computer chips and solar cells, and both require a surface coating before use. This coating requires a lot of heat and energy to run in a passivation process, making it a costly step. A group of MIT researchers wrote in the journal Advanced Materials they have found a way to passivate silicon at...

A 10.7 percent conversion rate has been achieved using less than 2 micrometers of raw material The Photovoltaics-Laboratory (PV-Lab) of EPFL's Insitute of Microengineering (IMT), founded in 1984 by Prof. Arvind Shah and now headed by Prof. Christophe Ballif, is well known as a pioneer in the development of thin-film silicon solar cells, and as a precursor in the use of microcrystalline silicon as a photoactive material in thin-film silicon photovoltaic (TF-Si PV) devices. A remarkable step...

A new way of making crystalline silicon, developed by U-M researchers, could make this crucial ingredient of computers and solar cells much cheaper and greener. Silicon dioxide, or sand, makes up about 40 percent of the earth's crust, but the industrial method for converting sand into crystalline silicon is expensive and has a major environmental impact due to the extreme processing conditions. "The crystalline silicon in modern electronics is currently made through a series of...

Silica Gel, made synthetically from sodium silicate, is granular, vitreous, highly porous form of silica. Silica is a naturally occurring mineral that is purified and processed into either granular or beaded form. It has a strong affinity for water molecules. Silica gel is commonly used as a desiccant where it is packed in vapor-permeable plastic in order to control local humidity in order to avoid spoilage or degradation of some goods. Due to their high absorption of moisture and...

Germanium is a chemical element in the periodic table that has the symbol Ge and atomic number 32. This is a lustrous, hard, silver-white, metalloid that is chemically similar to tin. Germanium forms a large number of organometallic compounds and is an important semiconductor material used in transistors. Notable characteristics Germanium is a hard, grayish-white element that has a metallic luster and the same crystal structure as diamond. In addition, it is important to note that...
